Efforts to tackle challenges in tablet manufacture are shaped by quality by design (QbD) and continuous manufacturing.

This article considers the different conditions to which the powder is subjected in the tableting process, and discusses which powder properties should be measured to accurately reflect likely powder behavior in the process.

Continuous manufacturing is increasingly noted as an important long-term objective for the pharmaceutical industry. PTE talks with Tim Freeman, Director of Operations at Freeman Technology, about some of the central issues involved in this transition, as well as the supporting role of relevant analytical technology.

The author explains how to gain an understanding of the relationships between powder characteristics and process performance to match filling-machine geometry to the demands of specific formulations.

The unit selected for wet granulation, whether it be a high shear mixer or a fluidised bed, has a marked impact on granule properties.

How to adapt a real time release approach to powder processing during drug-product manufacturing.

How effective powder characterization can lead to better powder understanding and control.

The needs of the pharmaceutical industry for powder testing technologies are changing, primarily for two reasons. The first is that global economics, and the economics and competitiveness of the pharmaceutical industry itself, are driving manufacturers towards achieving greater efficiency.

The needs of the pharmaceutical industry for powder testing technologies are changing, primarily for two reasons.

Enshrined in the concept of Quality by Design is the premise that optimized pharmaceutical manufacturing requires detailed understanding of products and processes. With this in mind, many benefits can be achieved by combining modern powder characterization techniques with real processing experience.

The current trend within the pharmaceutical industry toward more efficient development, manufacturing, and specification is fueling demand for analytical tools that provide highly relevant information. Effective powder characterization has a valuable role to play.
